I'm sure she has a great anime voice but when you're so used to Ootani Ikue's voice as Chopper because she brings that extra cuteness to him and then the voice is changed to something that doesn't relate to Chopper then that becomes a problem.

She actually made me like the character.
I originally watched City Hunter with the French dubs and I absolutely hated Kaori's character, and her voice was sooooooo annoying, but then I rewatched it in Japanese and I found her voice pretty cute, which made the character enjoyable.
